closed contract. Whose terms constitute the entire agreement between the contracting parties and no clause or provision can be changed or modified without mutual consent. An insurance contract, for example, is a closed contract whereas a construction contract may not be one. See also open contract.
The volt (symbol: V) is the derived unit for electric potential, electric potential difference (voltage), and electromotive force. The volt is named in honour of the Italian physicist Alessandro Volta (1745â1827), who invented the voltaic pile, possibly the first chemical battery.
Similar to the water pressure in a pipe, the pressure of electricity flowing through a wire is known as volts (voltage). This is the amount of electricity flowing through a wire. Weâve all seen the term KWH (kilowatt hour) on our electric bills. This refers to the rate of power flowing through a wire.
